When I started reading this topic, I knew someone who eventually call upon communism.

I'd just like to point out that, communism as the idea leads to equality of all and thus how can it be a tragedy, what people think of is where you have dictatorships under the name of communism such as Stalin who despite economically being left wing, he was so far right, he was worse than Hitler with his Gulags... the soviet union was socialist anyway at that stage. Other examples... china and korea where they are one party states... if they weren't one party states, they wouldn't be totalitarian/dicatatorships as let's face, when did Hilter have an election after he got rid of the weimar republic? The idea of communism is perfect, when taken into practice, one mistake and it goes off the road...

But I deem the greatest tragedy, America and the American revolution.

Would we be in a war right now if the americans weren't so arrogant? for "the defender of capitalism and freedom" they seem to have so many bugs... Kennedy was working towards detente with the soviet union (which did last for a while) and he was shot... by an american none the less (not to slip off into conspiracies). Then we have the gulf war in the early 1990s which if finished and done with then, would not have led to the current iraq war. They led the way for the invention of the atomic bomb killing scores in hiroshima and nagasaki which were really pointless seeing as how japan had practically lost the war but used more to "scare" the soviets. Their arrogance led the way for the KKK with WASPs and immigration, and to touch on a conspiracy here,. 1973, a report was published saying that if africa become industralised, it would be competition against america. the year later, AIDS was discovered...

for a supposedly free country, they have a lot of secrets...
